Abstract: Hot melt printed spacer membrane elements offer the unique advantage of applying any pattern on the membrane surface to act as the feed spacer material. This technique also eliminates damage to the active surface of the membrane by avoiding photo curing, either UV, light or other wavelengths of energy. By printing narrow features, the bending moment at the membrane surface imparted by the printed feature will be less than the bending moment imparted by a wider printed feature, thereby minimizing damage to the sensitive membrane coating.

Abstract: Printed spacer membrane elements offer the unique advantage of applying any pattern on the membrane surface to act as the feed spacer material. This is in contrast to conventional feed spacer mesh material that is uniform in thickness and density throughout the mesh. More open feed spaces can be utilized but may also result in higher stress concentration, and where the spacer material comes in contact with the opposing membrane leaf. This patent presents concepts for reducing the damage on membrane leaves by increasing the concentration of the print pattern near the center tube where the stress concentration on the membrane leaves is greatest, orienting the membrane sheets prior to rolling to minimize damage from slippage during rolling, moving the fold away from the first features to minimize leaks at the insertion point.

Abstract: Printed spacer membrane elements offer the unique advantage of applying any pattern on the membrane surface to act as the feed spacer material. This is in contrast to conventional feed spacer mesh material that is uniform in thickness and density throughout the mesh. More open feed spaces can be utilized allowing closer spacing between membrane sheets in the feed space which allows more membrane sheet to be wrapped around the membrane element—resulting in more permeate flow—while simultaneously reducing the pressure loss from the feed to reject end of the element. Unique design features of printed spacers dramatically improve performance of membrane elements in contrast to conventional feed spacer mesh elements in the prior art.
